The correct answer is option 3, Veldt. The grassland region of South Africa is commonly referred to as Veldt. This term is derived from the Afrikaans word "veld," which means "field" or "pasture." The Veldt is characterized by vast open plains covered in grasses and scattered shrubs. It is a significant ecological region, supporting a wide range of wildlife, including herbivores such as zebras, wildebeest, and antelopes, as well as predators such as lions and cheetahs. The grasses found in the Veldt are adapted to the dry climate and have deep root systems to access water from the underground. The region experiences a distinct wet and dry season, with most of the rainfall occurring in the summer months. The Veldt is an important grazing area for livestock, and agriculture, particularly cattle farming, is a common activity in this region. It is also a popular tourist destination, mainly for its wildlife and scenic beauty. So, the grassland region of South Africa is known as Veldt.
